Anti-vaccination sentiments are not a new phenomenon, with resistance to immunization dating back to the introduction of the smallpox vaccine in 1796. However, the recent COVID-19 pandemic has brought the issue of vaccine hesitancy into sharp focus. While the majority of scientific research emphasizes the importance and effectiveness of vaccines, there are some studies that explore the predictors of anti-vaccine attitudes and the role of perceived experts in spreading misinformation. These studies find that anti-vax positions are often rooted in scepticism and distrust of science, and that online content, social media, and conspiracy theories play a significant role in shaping attitudes towards vaccination.

What You'll Learn
Anti-vaccine attitudes and scepticism about science
The anti-vaccination movement has a long history, dating back to the introduction of the smallpox vaccine in 1796. However, the term "anti-vax" gained prominence in the early 1800s with the emergence of smallpox vaccine hesitancy. The movement has evolved and expanded over time, with activists expressing concerns about health impacts and safety, claiming that vaccines cause autism, for example. During the COVID-19 pandemic, anti-vaccine activists seized the opportunity to spread fear and discredit the vaccine development and evaluation process. They highlighted purported side effects and promoted conspiracy theories, aiming to undermine public confidence in vaccine safety and efficacy.
The influence of anti-vaccine attitudes is not limited to individual beliefs. It has also impacted policy and legislation. For instance, in Texas, lawmakers introduced legislation to remove routine vaccination requirements in schools, and the Republican Party platform now includes the right not to be vaccinated. Similarly, in California, anti-vaccine activists mobilised to broaden their following and lobbied state legislatures, gaining access to money, political influence, and broader audiences.
The spread of anti-vaccine sentiments is facilitated by various information providers, including online and social media sources. Social media platforms, such as Twitter and Facebook, have become breeding grounds for misinformation and conspiracy theories. Perceived experts, including medical professionals and biomedical scientists, have been identified as influential anti-vaccine nodes, spreading academic sources and connecting with a wide audience. Additionally, user-generated content on platforms like YouTube and blogs often provides misleading information about health issues, contributing to misconceptions.
It is important to note that the reasons for vaccine hesitancy are diverse, and not all individuals labelled as "anti-vax" or "anti-vaxxers" reject all vaccines. Some may only decline specific vaccines or oppose mandatory vaccination programmes, expressing distrust in the scientific evidence supporting vaccine safety and benefits. Understanding the complexities of anti-vaccine attitudes and their intersection with scepticism about science is crucial to effectively address this public health challenge.

Unrealistic expectations about science
The COVID-19 pandemic highlighted the importance of science in society, with scientific research and expertise offering a path out of the crisis. However, the rapid spread of the disease and the urgent need for a solution intensified unrealistic expectations about vaccine development and approval processes. Some individuals were concerned by the speed of vaccine development, doubting the safety and effectiveness of the vaccines. This skepticism was fueled by a decline in trust in science and state institutions, with some believing that hidden agendas or profit motives influenced the push for vaccination.
The role of perceived experts, such as medical professionals and biomedical scientists, in the anti-vaccine movement cannot be overlooked. These individuals, despite having expertise cues in their descriptions, actively spread misinformation and contribute to the spread of anti-vaccine sentiments. Their presence within anti-vaccine communities and their engagement with academic sources lend credibility to their anti-vaccine positions.
Additionally, unrealistic expectations about science are often shaped by individual levels of the "need for closure." This psychological trait influences the relationship between attitudes towards science and anti-vaccine positions. Individuals with a higher need for closure may be more susceptible to conspiracy theories and misinformation, as they seek quick and definitive answers that confirm their existing beliefs.
It is important to address unrealistic expectations about science to build trust in the scientific community and promote vaccine acceptance. This can be achieved through education and training and the dissemination of accurate and transparent information about vaccine development, safety, and efficacy. By improving scientific literacy and critical thinking skills, individuals can make more informed decisions about their health and wellbeing.

Anti-vaccine content and social media engagement
Social media has become a dominant source of information for many people, especially during the COVID-19 pandemic. However, it has also become a platform for the spread of misinformation and anti-vaccine content. Research has shown that anti-vaccine content often generates greater user engagement on social media. This can be attributed to the presence of a relatively small number of devoted and well-financed influencers who have amassed large followings on these platforms. These influencers spread misinformation and conspiracy theories, such as the myth that COVID-19 vaccines make women infertile, which can have harmful effects on their followers.
A report by the Center for Countering Digital Hate (CCDH) revealed that two-thirds of anti-vaccine content shared on Facebook and Twitter between February 1 and March 16, 2021, could be traced back to just twelve individuals, known as the "Disinformation Dozen". Despite this knowledge, social media companies have been criticized for their ineffective enforcement of rules regarding dangerous misinformation. For instance, out of the twelve members of the Disinformation Dozen, only three have been comprehensively removed from one of the three platforms (Facebook, Instagram, and Twitter).
The anti-vaccine movement is fueled by a combination of factors, including the influence of perceived experts, the presence of echo chambers, and the lack of engagement from health experts in online discussions. Perceived experts, including medical professionals and biomedical scientists, have been found to occupy important positions within anti-vaccine communities on Twitter, receiving significantly more engagement than other individuals. These communities exhibit strong in-group support, with homogeneous opinions that rarely welcome opposing views. Additionally, Facebook groups provide echo chambers for anti-vaxxers to recruit the vaccine-hesitant, further spreading misinformation. While health experts attempt to address conspiracies and prejudices on platforms like YouTube, their involvement often ends there, leaving discussions among laypeople without further professional input.
The spread of anti-vaccine content on social media has significant public health implications, contributing to vaccine hesitancy and potentially compromising public confidence in future vaccine development. As access to technology continues to improve, it is crucial that social media companies take more effective action to address the dissemination of harmful misinformation.

The role of perceived experts in anti-vaccine communities
The COVID-19 pandemic has brought to light the importance of scientific research and expertise in addressing global health crises. However, the emergence of anti-vaccine movements has complicated public health efforts, with individuals and groups expressing scepticism about science and spreading misinformation. Within these anti-vaccine communities, the role of perceived experts, including medical professionals and biomedical scientists, has been significant.
Perceived experts have occupied influential positions within anti-vaccine communities, leveraging their expertise to spread anti-vaccine sentiments. A study by medRxiv in 2023 analysed over 4.2 million Twitter posts and found that perceived experts were prevalent within the anti-vaccine community, sharing academic sources at higher rates than other members. These individuals served as central nodes and bridges between the anti- and pro-vaccine communities, receiving significantly more engagement than others.
The presence of perceived experts in anti-vaccine communities underscores the complexity of the issue. While these individuals may have credentials in medical or scientific fields, their stance against vaccines contributes to the spread of misinformation and shapes the attitudes of others. Their expertise lends a sense of credibility to their anti-vaccine positions, making them influential figures within these communities.
The anti-vaccine movement is not new, with resistance to immunisation dating back to the introduction of the smallpox vaccine in 1796. Over time, anti-vaccine activism has evolved, leveraging social media and political alliances to gain traction. In the context of COVID-19, anti-vaccine activists have seized opportunities to discredit vaccine trials, spread conspiracy theories, and undermine public confidence in vaccine safety.

Anti-vaccine activism and political action
Anti-vaccine activism has become a significant political force, gaining visibility and funding, particularly in the United States. This has enabled anti-vaccine groups to expand their reach, sue federal agencies, and organize activists at the state level, as well as increase their influence internationally. These groups have been described as well-funded and amplified, with some having annual revenues in the millions.
The anti-vaccine movement has been particularly active in spreading misinformation about the COVID-19 vaccines. A study of Twitter data revealed that perceived experts, such as medical professionals and biomedical scientists, played a significant role in the anti-vaccine community, sharing academic sources and acting as central nodes and bridges between the anti- and pro-vaccine communities. These perceived experts received a high level of engagement, contributing to the spread of misinformation.
Social media platforms, such as Facebook, have also been identified as sources of vaccine resistance, with individuals relying solely on these platforms for information being among the most vaccine-resistant. Conspiracy theories and inaccurate statements shared by right-wing media outlets have contributed to the spread of misinformation, with individuals consuming this information more likely to express misinformed opinions.
The political nature of the anti-vaccine movement has been reflected in the coverage of the COVID-19 pandemic, with government efforts at various levels facing challenges due to inadequate power, insufficient political will, and a lack of perceived legitimacy by vaccine refusers. The heavy-handed response to vaccine refusal has been criticized as counterproductive, with recommendations favoring a networked approach involving collaboration between public health agencies and diverse stakeholders to provide accurate and timely vaccine-related information.
The anti-vaccine movement has also targeted childhood vaccinations, with lawsuits funded by anti-vaccine groups leading to religious exemptions in mandatory vaccination policies. Additionally, some anti-vaccine activists have promoted the belief that autism is caused by vaccines, despite scientific evidence to the contrary, further contributing to mistrust in science and public health authorities.
